ádní

ádný is not a standard word in Czech. It is generally regarded as a misspelling or nonstandard variant of the negation determiner žádný, which means "no" or "not any." In standard Czech, the form without the initial ž (i.e., ádný) does not occur as a separate word and is not recognized as correct in contemporary usage.

In modern Czech, žádný is used before a noun to express negation of quantity or existence. Examples include nemám žádný čas (I have no time), není žádný důvod (there is no reason), and žádný z nás (none of us). The word agrees with the noun in gender and number, with masculine, feminine, and neuter forms such as žádný dům, žádná žena, and žádné dítě. It also functions as a pronoun in phrases like Žádný z nás (None of us). The term is common in both spoken and written Czech and is frequently found in negative constructions.

Declension and usage follow standard Czech adjective inflection. The forms change by case, number, and gender, while the meaning remains a negation related to the noun that follows. Prepositional phrases may require the genitive form, as in bez žádného důkazu (without any evidence).

Etymology and cognates: ž̌ádný is cognate with related Slavic forms, such as Slovak žiadny, used similarly to express negation. The Czech form with the initial “ž” is the normative standard; the variant without the diacritic is generally considered incorrect in modern Czech.
